21  // Note that if this bean does NOT implement any interfaces, then CGLIB is used to
22  // generate proxies for it. If it implements one or more interfaces, then the
23  // java.util.proxy module is used to generate proxies for it instead, unless
24  // CGLIB is explicitly forced to be used.
25  //
26  // Presumably Spring is assuming that the interface it implements is a
27  // "business interface" that users of the bean are coded to.
28  //
29  // However the type of proxy has interesting side-effects: a CGLIB proxy can
30  // itself be proxied by CGLIB. However a JDK proxy cannot; that generates a
31  // <i>final</i> class which CGLIB simply cannot generate a subclass of.
